Beginner Spy Tutorial: Your First DIY Mini FM Bug Transmitter
FM bug transmitters are simple electronic projects that can transmit conversations to any FM radio. The range is usually small at around 100 feet, but the project is simple enough for a beginner. What you need to start off with is a plastic mint box (definitely not tin) and some basic PCB skills. The FM bug transmitter parts list includes the basics such as including a variety of transistors, capacitors, resistors, a button battery, and a microphone.
The circuit fits in a tiny mint box which is smaller than a typical USB drive. The FM bug transmitter is a fun project and also teaches a lot about basic electronics and radio frequency modulation. Note: it’s illegal in most countries to record people without their permission. Check out more of our DIY spy projects:
